The contact owns a 2009 Hyundai Sonata. The contact stated while driving at an undisclosed speed, the contact heard a loud grinding noise coming from the rear of the vehicle. The contact took the vehicle to a local dealer to be inspected. The contact later discovered that the dealer only did a visual inspection of the brake pads and rotors. The mechanic stated that there were metal shavings from the brake pads and that the contact should wash the wheels to clear the metal shavings. The wheels were washed as instructed; however, the failure persisted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 181,000.

The problem as reported by so many others that the rear brake system has an inherent failure in the caliper/rotor/brake pads. I have vested nearly $2500 on the three for mentioned parts and labor over last 4 years. Between Midas and now a private mechanic have tried better lube on slide pins but the problem still persists. A little research states that the caliper piston doesn't retract from the rotors and in turn heating up the brake components to the point of failure. Some Law firms have stated the problem is a production flaw my problem with a system with this failure rate isn't recognized by the Hyundia. Calipers should simply last 80 to a 100 thousand miles under most driving conditions. Looking forward to your response. Kerry yakel

Complete break system as been done as well as tires with rotations, having to replace brakes and rotars often. Continues to pull hard to right while driving and is far from a smooth ride. When breaking the car feels to pull forward. The emergency break does not work at all. This feels like a never ending issue. The car seems to sit low on one side, have to take it to get looked at.

Check engine light is on. Hecu internal failure. Active dtc present: C1237 primary pressure sensor signal. Sensor failure inside the ABS control cycle. Values at pressure sensor changed from 0.3 bar to 78.0 bar; no change in supply voltage. Supply voltage constantly at 14V. Hyundai has mentioned that there are no active recalls and that this part is life threatening if it fails - but since the warranty has expired they are shying away. Online there are several known issues with hyndai and hecu. Specially for models before 2009. Its hard to believe that Hyundai is not aware of this problem and seems like they are avoiding their responsibility and playing with human life. Would appreciate if the government can do something.

Rear end of vehicle sways around as if driving on ice. Feels exactly like descriptions of issue with recall 13V354000. Hyundai says vehicle is not included in recall. Excessive play in rear end, and very noticeable burning smell coming from rear end after driving. Causing excessive wear of rear brakes and tires. Has caused rear brake hoses to fail. Occasionally brake pedal sinks to floor while driving in stop and go traffic. While traveling at highway speeds, vehicle feels as if a gust of wind could send it off the road. Need to do a ton of steering to keep the car going straight. Front end was aligned 25,000 miles ago.

My brake light stop switch broke into pieces with normal use so the brake lights stay on when car is turned off. My front brake hose sprung a fluid leak that made the brakes fully stop working in the middle of a drive. The front brake hose split and cracked prematurely cuasing the brale fluid to empty out. The brake pedal went straight to the floor without stopping the vehicle when this event happened during a drive. My ESC light is on big probblem im assuming. My passenger air bag light is on as well both indicate are off and non working.

I own a 2009 Hyundai Sonata. While operating I noticed a significant decrease in speed, coasting, fuel economy, and braking distance. Upon parking my car I smelled burning brakes. As I walked past the driver rear tire I could feel the heat radiating from the tire. I didn't dare touch the rim for fear it would burn me. Diagnosis revealed a seized rear driver brake caliper piston. This caused ruined the rear brakes and put undue stress on the front brakes. I had to replace the entire braking system as they had all become a safety hazard. I purchased an extended warranty which covered the rear caliper replacement but nothing else. Burning through brakes is a serious safety hazard. I haven't notified the manufacture of the failure. The failure mileage was 73,000.

Stop lamp switch replacement. On 01/14/17 I had an appointment at plaza Hyundai located at 2700 nostrand ave, brooklyn NY 11210 to replace my stop lamp switch. They did not have the part in stock at that time. The part was ordered on 01/14/2017 and as of this writing (02/17/2017) they have not received the part and have no estimated time or arrival on the part. No one even notified me that the campaign was not completed. I had to come back in the following day 01/15/2017 because my break lights were not turning off. At that time they attempted to charge me for a diagnostic, but I advised the manager that I was there less than 24 hours ago to address the stop lamp switch, which may have been causing the issue. They told me at that time that the part was still on order. They refuse to give me an eta. I called Hyundai's corporate office, and they could not get an answer from plaza auto either. This is a serious recall as it effects my ability to signal that I'm breaking. I will attempt to go to another service department or remedy myself, but I think that this is unacceptable.

Rear brake calipers have seized at least 7 times, causing me to need to replace them. I'm at 115,000 miles and have had the left one seize, destroying the rotor and pad 4 times, and the right one seize 3 times (once recurring within 15,000 miles of replacement). The car has been repaired at different shops, but the problem keeps recurring. First time occurred shortly after 30,000 miles. Occurs every 1-2 years since then. Most recent occurrence is now (car is being repaired this morning, left rear caliper/rotor/pad). Noticed massive shimmying this time. Previous times have been noticed from: Grinding noise, car won't accelerate over 10 mph (locked in engaged brake mode that time), and severe bucking while being driven.

I have owned this car since July 2014. I purchased the car with 54K miles. I currently have 107K miles and it's October 2016.I have had to replace my brakes 4 times, specifically because the rear brake calipers fail causing brakes to lock while driving producing significant heat and damage to the brake components. The problem also cause a significant loss of fuel economy. It appears this is a common problem on this vehicle and a recall has been put in place starting in model year 2011. The recall needs to be extended to include 2009 model year vehicles

Purchased my 2009 Sonata in February 2009, by mid July I had to replace the rear brakes. I was a little surprised since the car was new and only had about 5000 miles. I was told that I was required to check the brakes every 3500 miles and it wasn't covered under warranty, not even the 5 year bumper to bumper warranty. It is now 2016 I have had to replace my rear brake calipers, pads and rotors every 6 months at a cost of over $400 every time. There is a great deal of grinding, heat and massive vibration in the rear while braking to this point. I have returned my car for both current recalls (not applicable to brakes). With so many models having the same issues, its very disappointing that Hyundai will not repair their faulty engineering and the NHTSA has not investigated this major safety issue with braking systems in these cars.

Upon accelerating up an entrance ramp to the highway, car accelerated at an unreasonable rate of speed tried using brakes, but they were gone. Car hit speeds of 60/65 mph for more than 3 miles on a turnpike. Parking brake did not work, brake pedal was down to the floor and I could not control the speed of the auto. After traveling more than 3 miles, in the shoulder, I put the gear into neutral and the car began to slow down and finally stop. Towed from turnpike to dealership. Know there have been problems with the 2006 model, but is there anything similar to my experience with the Sonata 2009.
